Question
A boat covers 540 km upstream and downstream in 't'
time. If the speed of the stream is 8 km/h and the speed of the boat is 10 km/h then find the value of 't'.Solution
Let the speed of boat in still water =B and speed of stream =S then B=10km/h and S= 8km/h So now Speed of Boat in upstream = B-S=2km/h Speed of Boat in Downstream =B+S=18km/h ATQ- t=540/18+540/2 =30+270 =300hours.
